Model 1917 Retail Price: ¥45,980 I purchased this several years ago, but due to frequent business trips, I never opened it and it's been stored in the closet. I am selling it because my Surface broke and I disposed of it. The box has minor scratches. Please check the manufacturer's website for details. - I cannot answer questions about specifications or operating environment. - I do not smoke. - I will ship using recycled packaging materials. - No returns or exchanges to prevent swapping. - Please refrain from bidding if you are overly concerned about minor details. Thank you.
